Unit 2-Paola lopez

nerve

A bundle of fibers that receives and sends messages between the body and the brain.

elastic connective

A connective tissue that is composed mainly of elastic fibers is referred to as elastic tissue.

holocrine gland

A gland releasing a secretion consisting of disintegrated cells and their secretory products into the lumen.

exocrine gland

A gland that makes substances such as sweat, tears, saliva, milk, and digestive juices, and releases them through a duct or opening to a body surface.

extra cellular matrix

A large network of proteins and other molecules that surround, support, and give structure to cells and tissues in the body.

leukocytes

A type of blood cell that is made in the bone marrow and found in the blood and lymph tissue.

erythrocytes

A type of blood cell that is made in the bone marrow and found in the blood.

merocrine gland

A type of exocrine gland in which the secretory products are released without resulting any damage to the cell.

apocrine gland

A type of gland that is found in the skin, breast, eyelid, and ear.

mast cells

A type of white blood cell that is found in connective tissues all through the body, especially under the skin, near blood vessels and lymph vessels, in nerves, and in the lungs and intestines.

macrophages

A type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells. Enlarge.

endocrine gland

An organ that makes hormones that are released directly into the blood and travel to tissues and organs all over the body.

gland

An organ that makes one or more substances, such as hormones, digestive juices, sweat, tears, saliva, or milk.

neuroglia

Any of the cells that hold nerve cells in place and help them work the way they should

areolar

The area of dark-colored skin on the breast that surrounds the nipple.

reticular

The thick bottom layer of the dermis (the inner layer of the skin).

stratified squamous

This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or protection against water loss

osseous tissue

Tissue that gives strength and structure to bones.

simple columnar

a single layer of cells that are taller than they are wide, with an oval nucleus usually located towards the basal region of the cell

simple squamous

a single layer of flat scale-shaped cells

lacuna

a small cavity, pit, or discontinuity in an anatomical structure.

blood

a specialized body fluid.

goblet cells

a specialized type of epithelial cell that secrete mucins

duct

a tube or vessel of the body through which fluids pass.

simple cuboidal

a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.

regular connective

are connective tissues of a group or bundle of dense, robust, and large collagen fibers that hold the tissue and provide strength to it

neuron

are the fundamental units of the brain and nervous system

osteo-

bone

basal surface

bottom edge of the cell or tissue adjacent to the basement membrane

chondro-

cartilage

cyte-

cell

muscle tissue

composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.

adipo-

fat

osteocytes

former osteoblasts that become surrounded by unmineralized matrix (osteoid) during bone formation;

adipose

is a connective tissue that extends throughout your body.

exocytosis

is a process by which a cell transports secretory products through the cytoplasm to the plasma membrane.

stratified cuboidal

is a rare type of epithelial tissue composed of cuboidally shaped cells arranged in multiple layers.

Basement membrane

is a thin, dense layer of extracellular matrix that lines most human tissues forming the supporting structure and scaffolding for epithelial tissue and separates different types of cells, such as nerve cells and muscle cells.

bone

is living tissue that makes up the body's skeleton.

stratified columnar

is made up of multiple layers of epithelial cells.

fibrocartilage

is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons

elastic cartilage

is your most flexible cartilage.

epithe-

laid on, covering

pseudo- stratified

of, relating to, or being an epithelium consisting of closely packed cells which appear to be arranged in layers but all of which are in fact attached to the basement membrane.

exo-

outer, outside

erythro-

red

ground substance

s an amorphous gelatinous material.

free surface

surface not attached to other surfaces.

irregular connective

the intercellular matrix of which contains a dense irregular network of collagen and elastic fiber bundles.

hyaline cartilage

the most common type of cartilage in your body.

-ology

the study of

hist-

tissue
